The ongoing war on antibiotic resistance.
Researchers may have found a new way to reach deep-seated infections without wrecking the rest of the body. According to a study published in Military Medicine, scientists have successfully used a needle-free device to deliver medicine directly into the infected tissue. It pushes the medication through the skin rather than into the bloodstream, which helps avoid the common, dangerous side effects of antibiotics, such as kidney damage.
Science has rediscovered a “forgotten” skeletal tissue that could be the future of facial reconstruction.
A study in the journal Science describes the unique properties of lipo-cartilage, a fat-filled tissue found in our ears and noses. Unlike typical fat cells that shrink or grow based on diet, the ones in this tissue maintain a constant size, offering a resilient material for 3-d-printing customized grafts. It opens a new door for regenerative medicine that could end the need for invasive rib-cartilage harvesting.
A common bedtime habit might be preventing your brain from performing its nightly “deep clean.”
Poor sleep is a precursor of neurodegenerative diseases, partly because it doesn’t give the brain a chance to remove waste. New research in the journal Cell, reveals that sleep allows the body to wash away toxic proteins associated with Alzheimer’s and dementia. However, ambien, a popular sleep aid, suppresses this process. Scientists worry long-term use of this medication may lead to neurological disorders.
Building public trust in science may rely on appearances.
According to a new study in Nature Human Behaviour, many americans – particularly women and people of color – report higher levels of confidence in scientific claims when they see themselves represented among the researchers. The findings suggest that demographic inclusiveness is not just symbolic, but essential for ensuring that scientific information successfully influences public policy and decision-making.
